l METAL can ann application mea February 1s, 1922. serial No. 537,361.'

citizen of the United States, residing at Pennside, Reading, in the county of- Berks I 5 and State of Pennsylvania, have invented acertain new and useful Improvement i n Metal Car Ends, of which the followlng 1s a full, clear, concise,and exact description,- referenc'e being had to the accompanying' drawings, forming a part of thisspeciication. This invention relates to improvementsin metal car ends.

One object .of the invention is to 4provide an eiiicient, durable and economical metal A more specific object ofthe invention is to provide a sheet metal end having great strength against endwise thrusts to prevent bulging, and which also affords great strength against vertical and horizontal forces which may be exertedonthe end/so that the metal end effectively serves to rigidify the car superstructure to prevent skewing or weaving.

In the drawings forming a part of this specifi-cation, Figure 1 is an elevational view of the end of a box car showing my improvements applied thereto. vFigure 2 is'a the section line 2-2 of Figure 1. Figure 3 is a vertical, sectional view corresponding to the section line v3--3 of Figure 1. Figure 4 is a side elevational view of the sheet metal end, detached. Figures 5 and 6 are sectional views corresponding to the section lines 5--5 and 6-6 respectively of Figure 1.

In said drawings, the carroof is indicated at 10, the side wallsgat 11', the corneryposts at v12, -the-end lplate' at 13 end fascia board at 14, center si s at 15, sidesills at 16, floor lat 17, buffer block or casting at 18, and end sill at 19:

The improved sheet .metal end proper, as shown, comprises preferably, an upper section or half A an a lower section or half B.

vThe u er-section A is provided with a integrally.l formed' strengthening indentations in .-the form' of co tions rtions intersect" 'in the vertical central diverging downwardlvgtherefrom, the oorhorizontal sectional view corresponding to' designated at 20,` 21,22, 23, 24, 25,;26,'127 and-28. 'The corrugations20to'124inclu- 'f ysive consist each :of two the'others progressively greater in extent untll theA maximum is reached at 24. In each upper outer corner of the top half or sectlon A of the end wall, arejthe other corrugatlons 25, 26, 27 and 28, parallelly arranged and progressively decreasing in length as they approach the corner, as clearly seen 1n Flgure 1. All of said corrugations 20 to 24 inclusive'have their lower lends termlnated in substantially a horizontal line, as clearly shown inFigure 1.

The bottom half 'or section B of the car end is provided with a similar series of but oppositely Varranged integral corrugation's 20a, 21a, 22a,- 238, 24e, 25a, 26a, 27a, and 28a.

Allof said corrugations 20a to 24 inclusive h ave their upper ends terminated in substantlally a horizontal line,l the ends of the corrugations, 2()l and'20a; and 21 andA 21a, etc.,

beirig disposedV vertically \opposite each other.

sidered in connection with the drawing, and assuming the end wall as. an entirety divided mto .four quarterl sections, it will be found that the corrugations in each quarter vsection are approximately perpendicular. to a diagonal of the end wall passingV therethrough and furthermore that the various From y the preceding description, V'consets of corrugations 20 and 20, 21 'and 21,

etc., form.,- in effect', diamond shaped corrugations of graduated extent outwardly.

fromthe center of theend wall toward the edges and top, except for the omissions which occur where the sheets of the upper and against -endwise thrusts occuring in service dueto shifting of the load or pressure from lloads of a more or less' iuid character, but

I also greatly strengthen. the end wall against any tendency to collapse or skew i from forces applied' thereto from either side or from the top or from the bottom. In other words,'th'e sheet metal end, when secured tothe sidewall, roof and Hoor structure'.

of the car, affords great strength to the superstructure in reslsting tendency of. thel superstructure to'- weavel or skew 1n direc-.-

tions transversely of the car. -iThe two sections A and B 'andsecured by a horizontally exseries of' rivets 29. To secure the lalcngits vertical sides, the car, end

ico

of the endrwall: A Egg 'are overlapped "as indicated at -b best in of thefengl an -13, asshown in Figures l and 3, the end plate being preferably rabbeted so as to leave the outer face of the sheet metal flush with the outer surface of the end plate `13. Atthe bottom, the lower panel B has its lower edge' extended inwardl horizontally as indicated at 31 the end silly19 being applied thereover. referably a short section of angle 32 is used on the outer side of the end wall opposite the buffer casting 18, said angle sect-ion 32 and inner angle iron 19 being riveted together through the sheet metal end wall. Y

` Owinof to the side anges 30 of the two panels and B, where they are overlapped, l preferably loffset'outwardly the flange 30 of the top panel A as indicated at 30 in Figure l and the lower edge of the panel A near the side is also preferably ofset as indicated at 30h, the latter offset however gradually merging into the lap joint as shown in Figure 3.

I- have herein shown and described what l now considervthe preferred manner of carrying out thev invention but the same is merely illustrative land I contemplate all changes and modiiications that come within the scope of the claims appended hereto.

Iclalm:

1. A sheet metal car end having strengthening indentations therein, all exten ing substantially parallel to diagonal lines of the end', all the indentations inv any one quarter section ofthe end being approximately at right angles to all of the indentations in an adjacent quarter section.

2. A sheet metal car end having stren thening indentations therein, all exten ing substantially arallel to diagonal lines of the end, the lndentations in an two adjacent quarter sections of the en being .approximately at right angles to each other, 4said end comprising upper and lower panels rigidly united.

3. A sheet metal car end having integrally formed corrugations therein, sa1d corru tions, in each quarter section ofthe en'd, e

ing all, parallel and all extending transverse to a diagonal line of the end passing through said quarter section.

4. A sheet metal car end having integrally formed corrugations therein, sa1d corrugations, in each quarter section of the end, being all parallel and all extending transverse to a diagonal line of the end passing through said quarter section, said end coin-- prising upper and lower panels rigidly united by a `horizontally extending lap joint.

5. A sheet metal car end having in the upper portion thereof, a pluralit of intersecting corrugations all diverging downwardly from a vertical centrally disposed line to substantially a common horizontal line and in the lower portion thereof, having a plurality of corrugations all diverging upwardly from said vertical line to a substantially common horizontal line.

6. A sheet metal car end having in the upper portion thereof, a plurality of intersecting corrugations diverging downwardly from a vertical centrally disposed line and in the lower portion thereof, having a plurality of intersecting corrugations dlverging upwardly from saidvline,-the lower ends of said first named v.corrugations terminating opposite the respective upper ends of the second named corrugations, said end being formed of two panels rigidly united by a horizontally extending lap joint.

' 7. A sheet metal car end comprised of an upper panel and a lower panel united by a horizontally extending lap joint, saidupper panel having integrally formed therein, a series of intersecting corrugations diverging downwardly from a centra-l vertically extended line and all terminating in a substantially common horizontal line and additional corrugations in the upper corners of the panel, said lower panel having similarly' arranged corrugations but extended in the opposite. direction.
